Shocking but true:
Your brush needs attention similar to what you give your hair. No matter what kind of brush you use, whether it be one with synthetic, metal, or boar bristles, it’s important to clean it on a regular basis.
You spend hours and hours deep conditioning your hair, co-washing it, clarifying it. You use essential oils like peppermint and tea tree to cleanse the scalp and stimulate blood flow. You understand that clean hair means growth. You do these things on a strict schedule to prevent unsightly buildup.
So why would you undo all of your effort by using a dirty brush?
